Novice in need of help please

We have a domain name (ucnorfolk.com) purchased at go daddy and hosted at a different place. I'm trying to build a new website for this domain name using wp, and would like to manage it through wp. How do I make this happen and is there a fee?

If you are referring to a WordPress.ORG install the this is the correct forum for your software http://wordpress.ORG/support/ If you have not registered a WordPress.org username account yet you can do so on the top right hand corner of the page I just linked to so you can post to those support forums.

There is no upgrade you can purchase from WordPress.com that changes any of that. If you do require an eCommerce site, advertising, affiliate links, paid or sponsored content you can hire a web host and get a free software install from http://wordpress.org
